Load pull characterization is an essential tool to increase the efficiency of power amplifiers. Due to time and cost, vendors have historically performed load pull during design. Today, however, the ...

Figure 1. Schematic of a Doherty PA Techniques such as Doherty amplifier structures extend high-efficiency device operation to lower power levels, allowing for significantly improved average PA ...

On visiting a high-performance GaAs fab, I was shown a problem with the measurement system. The on-wafer test system was calibrated using a power meter and on-wafer standards, using the built-in ...
